Title: Soil pressure sensor for transplanter
Inventor: ISHITOBI YOSHIO
IPC: A01C11/02
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To provide the subject sensor, which secures a constant sensing load acting on a float by providing its sensing link mechanism with an elastic mechanism to push the float upward. SOLUTION: This soil pressure sensor is for a transplanter vehicle equipped with a planting section having a float 14, a hydraulic cylinder device 19 to support the transplanting section in such a way to freely move it upward or downward, and a hydraulically operated control valve 35, connected to the float 14 via a sensing link mechanism 15, to control the hydraulic cylinder device 19. The hydraulically operated control valve 35 is controlled, based on soil pressure load acting on the float 14, and the sensing link mechanism 15 is equipped with an elastic mechanism 54 on the transplanter side. This elastic mechanism 54 presses the float 14 to move upward, even when, e.g. the transplanting section is equipped with a fertilizing machine, absorbing resistance of the nozzle of the fertilizing machine or the like against upward motion of the float 14 and thereby keeping the float 14 exposed to an almost constant sensing load.

Title: Prediction output d/a converter
Inventor: TAKAYAMA TAKEYUKI
IPC: H03K7/08
Filed: 1991-10-16
Abstract: PURPOSE:To reduce a delay time from an input signal of an arithmetic operation circuit till a PWM output by implementing prediction PWM conversion based on data of one preceding sample or over. CONSTITUTION:A prediction output PWM converter 9 uses a PWM conversion synchronizing signal 7 to fetch an output of one preceding sample from an arithmetic operation circuit 3 stored in a delay element 8 simultaneously as the sampling of an A/D converter 2 and applies PWM conversion into a positive or a negative pulse. This is the prediction PWM conversion. After the arithmetic operation in the circuit 3 is finished, an error between the output of one preceding sample stored in the element 8 from the circuit 3 and an output of the circuit 3 substantially to be PWM-converted is calculated. Then the positive or negative correction pulse is outputted in a timing after lapse of a prescribed time after the prediction PWM conversion is started. As a result, the entire delay time is considerably reduced regardless of the arithmetic operation time by the arithmetic operation circuit 3.

Abstract: PURPOSE:To disuse a clamping bolt and to fix a punch and die quickly and correctly by engaging a piston with the clamp ring which fixes a die, etc. and by performing the clamping and release of the ring by ascending and descending the piston. CONSTITUTION:A piston 35 is fitted to the clamp ring 21 which fixes the die 13 fitted inside a support plate 1 and a spring 35 is inserted into a cylinder 23 and a oil pressure means 30 is linked as well. The fixing structure of the upper and lower punch 12, 14 is made similar as well. In case of the change of a die 13, etc., the piston 35 is ascended against the spring 25, when the oil pressure is fed into the cylinder 23, and the pressing of the clamp ring 21 is released. In case of clamping, the oil pressure is released and clamping is made by the spring 25. Consequently the bolt for clamping becomes unnecessary and the clamping and release can be performed quickly and correctly.

IPC: H02M7/155
Filed: 1994-10-07
Abstract: PURPOSE: To decide a compensating current in a short time without being affected by the accuracy or frequency characteristic of a detector which detects the load current or load voltage of a thyristor rectifier by fetching the magnitude and phase of each harmonic of a higher harmonic current from a memory means in which the magnitude and phase are stored in advance and deciding the waveform of the higher harmonic current. CONSTITUTION: A gate control signal 3 fetched to an input means 5 is transferred to a higher harmonic current waveform deciding means 7 and the means 7 leads out the waveform of a higher harmonic current corresponding to the gate control signal 3 by making access to a memory means 6 which stores the waveform in advance and decides the waveform as the waveform to be compensated. The decided waveform is inputted to a compensating current generating means 9 and the means 9 generates a higher harmonic current 8 having the waveform of the same magnitude and same phase as those of the decided waveform and makes the current to flow to a bus 1.  Therefore, the higher harmonic current can be compensated without being affected by the accuracy and frequency characteristic of a detector which detects the load current or load voltage of a thyristor rectifier and, at the same time, the calculating time of the compensating current 8 can be made shorter.

Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To eliminate a driving source specially for moving a thermal head up, down, and facilitate setting and detachment of ink sheets, by adapting a pressure roller to scan along a convex face of a roller guide when the thermal head operates to print, and to move along a concave face when the thermal head returns. SOLUTION: When a head transfer part 9 moves right, a pressure roller 7 comes in touch with a projecting part of a roller guide 10 and consequently is pressed down. As a result, a head-pressing part 6 presses down a head support part 4 via a head-pressing spring 8. A thermal head 3 is pressed to a face of a paper 1 via an ink sheet 18, thereby performing printing. Then, the head transfer part 9 and a head guide shaft 15 are moved from the depth to the front, namely, in a sub scan direction by a pitch of projections and dips of the roller guide 10 along a pair of guide holders 11, 13. Accordingly the pressure roller 7 moves to a groove position as the dip of the roller guide 10.

Filed: 1994-11-01
Abstract: PURPOSE: To enable the liquid compression diagnosis of a compressor without needing any prototype by envelope detection of a piezo-electric signal from a piezo-electric element mounted on the external appearance part of the compressor. CONSTITUTION: A sensor 2 consisting of a piezo-electric element mounted on a compressor 1 detects a signal caused by the liquid compression of the compressor 1, and the detected signal is subjected to envelope detection by an envelope detection apparatus 3 and indicated on an output apparatus 4.

Abstract: PURPOSE:To prevent the generation of a gap between a cover and a metallic base by constituting an abutting part between the base and the cover only of a waveguide side end part. CONSTITUTION:The coaxial connector side end part of the metallic base 11 is cylindrically formed, its outer peripheral part is covered with a seal member, a small diameter part 14 into/with which the cylindrical part of the end part is inserted and engaged is formed on the cover 5, and the cover 5 is fastened with the base 11 by a nut 15 screwed with a coaxial connector 4. Since the abutting part between the base 11 and the cover 5 is constituted only of the waveguide side end part (the flange 1b of the base 11), the cover 5 can be surely abutted upon the collar part 3 of the flange 1b even when a long or short cover 5 is formed.
